As a bonus this already fixes several bugs caused by the botched texture scaling implementation the original texture manager came with.
System cursors are currently disabled because they rely on functionality that needs to be moved to different classes.
- disallow bool as a return value for direct native calls because it only sets the lowest 8 bits of the return register.
- changed return type for several functions from bool to int where the return type was the only thing blocking use as direct native call.

* use I_Error instead of I_FatalError to abort. I_FatalError is only for things that are not recoverable and should not be handled outside of error cleanup and rethrowing.
* only catch CRecoverableError in JitCompile. Everything else should fall through to the outermost catch block.
* Do not I_FatalError out after handling the exception locally. Just print an error and return null, indicating failure.
